JEE Main 2025 Physics question
In the experiment for measurement of viscosity '' of given liquid with a ball having radius R, consider following statements. A. Graph between terminal velocity V and R will be a parabola B. The terminal velocities of different diameter balls are constant for a given liquid. C. Measurement of terminal velocity is dependent on the temperature. D. This experiment can be utilized to assess the density of a given liquid. E. If balls are dropped with some initial speed, the value of will change. Choose the correct answer from the options given below:
Answer: (2)
Solution
, so V vs R is parabolic (A), depends on temperature (C), and can determine density (D)
